gular manner to a median columella Ranunculacece and 

 Geraniacete. 



1699. Second order, S. vaginatce. Trees having many- 

 seeded carpels, coalesced like the style, Theacece, Tili- 

 acece, Mceocarpacece. 



1700. Third order, 8. axonales. Bushes and shrubs 

 with free, mostly simple, leaves, ovaria, mostly one-seeded, 

 and arranged in a circle around the mediate axis or 

 columella; anthers bilocular Hermanniacea, Dombey- 

 acece, Sterculiacete, and Buttneriacea. 



1701. Fourth order, S. for ales. For the most part 

 trees, having frequently divided leaves and similar ovaria, 

 yet mostly many-seeded and connate Malvaceae and 

 Bombacece. 



1702. Fifth order, S.fmduarice. Corollae mostly sex- 

 anary, ovaria in a circle without a columella Magnoliacece, 

 Menispermaceos, Ditteniacea, Anonacece. They divide 

 into sixteen families. (Vid. Tab. B.) 



CLASS XL 



Ovarium-planfe. 



1703. Hypogynous Polypetalae with perfect multi- 

 locular ovarium Polyyalea, Meliece, Aurantiacece, Plata- 

 nacetB, Malpighiea, Sapindea. 



1704. While in the preceding class the number of the 

 carpels was usually indeterminate ; it is here limited to 

 three and five. In the one, they usually stood around a 

 middle columella or axis, in the other, they form a true 

 capsule with perfect partition-walls or septa, and a single 

 style. The number of the seeds is moderate, i. e. there 

 are more than one, but they are easily counted. They 

 are therefore of mediate size, having no kernels, as is the 

 case in the nuts, but also no granules, as in the berries or 

 poppy capsules. In the preceding class the fruits were 

 rare; here they occur frequently in the upper orders. 

 The number of the floral parts is, throughout the present 

 class, five, that of the stamina five or ten, and they are
